Unique Rubber Bunker fitting for iconic british S10 gas mask, which allows you to capture a breath for advanced play with this gas mask.

NEW!!! We have version for similar FM12 gasmask!

Fitting is easy to fix to the gasmaks, gas mask is not destroyed and can be restored to original  system anytime. At first, disassembly drinking system tube  by moderate pull on the tube. Attach provided rubber O-ring on the groove around breath-out valve on S10 gas mask (instead of the original drinking tube).  And finally clip the fitting on the mask and enjoy!

NATO screw is by default centered, off-center variant can be selected. 

Colours and thread style of fitting are optional.

Please select propriate size of platform, S10 differs from FM12! 

S10 have valve of drinking tube on right side, FM12 have this valve on left side. FM12 have usualy two inlets for air (for two fitler canisters), S10 have on right side of mask just voice port. Sides are from view of person wearing a mask on head. FM12 is litle bit smaller in dimensions for platform.          

F - inner NATO40 thread (usualy on gas masks) 

M - outer NATO40 thread (usualy on filters)


Rubber O-ring is included.

Basic thread for most of common gas masks and accesories is based on NATO40 standard thread. We designed special thread compatible with "west" (NATO gasmask system, like polupar british  S10 gas mask) and "east" (e.g. soviet GP-5 gas masks).


Gas mask itself and hoses are not part of this item.
